Perl isn't supported by android marketplace and the apple app stores. I didn't expect you to do research for me, just to point me in the right direction if you knew what you were talking about, but it doesn't seem like you do. You didn't read my question, I stated that perl couldn't be used for the tablet part, outlined what the server side component should do and asked if perl was suitable for that task.
But thanks all the same, for jumping to conclusions and bashing the newbie. Did you even try a websearch for "bluetooth" or "network", several pages in and the results have nothing to do with what I've asked. Don't give such stupid advice. If you don't know the answer, or don't want to help, fine, just don't pounce on those requesting help.
